Our primary hypothesis is that kinematic changes will be detected after OMT for motions in the primary direction of the passive diagnostic test motions (cervical side-bending right and left), as well as angular rotations (deviations) occurring around these motions. Our secondary hypothesis is that examination of the kinematic data will provide objective inter- and intra-examiner data to assess similarities/differences occurring during the passive clinical exam before and after OMT. Lastly, we hypothesize that significant differences in the kinematic patterns will result between the two subject groups.
